ACKNOWLEDGEMENTS 

The Drinking Water Surveillance Program (DWSP) employs a team 
approach requiring the co-operative effort of the Ministry of 
the Environment (MOE) staff from Water Resources and 
Laboratory Services Branch and the Regions, as well as plant 
operational staff from the Municipalities. 

This annual report was produced by the DWSP Group (Ron 
Hunsinger, Peter Bohm, Carol Sackville-Duyvelshof f , Chris 
Fung and John McGrachan) and by Pat Lachmaniuk (on 
developmental assignment to the Drinking Water Section) . 
Helpful input and reviews were received from Drinking Water 
Section Staff, in addition to reviews by other MOE and 
municipal personnel. 



EXECUTIVE SUMMARY 

DRINKING WATER SURVEILLANCE PROGRAM 

STONEY POINT WATER TREATMENT PLANT 
1987 ANNUAL REPORT 



The Drinking Water Surveillance Program (DWSP) for Ontario is a 
monitoring program providing immediate, reliable, current 
information on drinking water quality. The DWSP officially began 
in April 1986 and is designed to eventually include all municipal 
supplies in Ontario. Currently, 44 plants are being monitored. 

The Stoney Point Water Treatment Plant is a conventional 
treatment plant which treats water from Lake St. Clair. The 
process consists of coagulation, f locculation, sedimentation, 
filtration and disinfection. This plant serves a population of 
3,500 and has a design capacity of 4.45 x 1000m3/day. 

Raw and Treated water samples were analyzed for approximately 160 
parameters in June and November. Parameters were divided into the 
following groups Bacteriological, Inorganic and 
Physical (Laboratory Chemistry, Field Chemistry and Metals) and 
Organics (Chloroaromatics, Chlorophenols, Pesticides and PCB, 
Phenolics, Polynuclear Aromatic Hydrocarbons, Specific Pesticides 
and Volatiles) . 

A summary of results is shown in Table 1. 

Due to the sampling frequency, full evaluation of the 
bacteriological quality of water could not be made. Routine 
bacteriological monitoring as outlined in the Ontario Drinking 
Water Objectives (ODWOs) is carried out by the operating 
authority. 

Inorganic and Physical parameters (Laboratory Chemistry, Field 
Chemistry and Metals) were all below applicable health related 
ODWOs . 

Of approximately 110 Organic parameters tested for, none exceeded 
health related guidelines. 

Many of the substances detected are naturally occurring or 
treatment by-products. 

For 1987 the DWSP sampling results indicated that the Stoney 
Point Water Treatment Plant produced good quality water. 



SOMMAIRE 

PROGRAMME DE SURVEILLANCE DE L' EAU POTABLE 

STATION DEPURATION DE L' 5AU DE STONEY POINT 
RAPPORT ANNUEL 198 7 

Le Programme de surveillance de l'eau potable (PSEP) de 1' Ontario 
fournit des informations immediates, fiables et a jour sur la 
qualite de l'eau potable. Le PSEP a debute of f iciellement en 
avril 1986. II est destine a englober tous les reseaux municipaux 
d' alimentation en eau de 1' Ontario. Actuellement, 44 stations en 
font partie. 

La station d'epuration de Stoney Point est une station classique 
qui traite l'eau du lac Sainte-Claire . Le traitement comporte la 
coagulation, la floculation, la d^cantation, la filtration et la 
disinfection. Cette station, qui dessert une population d' environ 
3 500 habitants, a une capacite nominale de 4,45 x 1 000 m3/jour. 

Des pr^levements d'eau brute et d' eau traitee ont ete analyses en 
juin et en novembre par rapport k environ 160 parametres dans les 
categories suivantes : bacteriologique, inorganique et physique 
(analyses en laboratoire et sur place, presence de metaux) et 
organique (composes aromatiques chlores, chlorophenols, pesticides 
et BPC, derives phenoliques, hydrocarbures aromatiques 
polynucleaires, pesticides particuliers et composes volatils) . 

Le tableau 1 resume les resultats obtenus. 

En raison de la frequence des prelevements, on n'a pas pu evaluer 
tous les aspects de la qualite bacteriologique de l'eau. 
Cependant, comme on le recommande dans le cadre des objectifs 
relatifs A la qualitfe de l'eau potable en Ontario, un contrdle 
bacteriologique est effectue par 1' exploitant . 

Les mesures des parametres inorganiques et physiques etaient 
inferieures aux limites applicables fix^es par l'Ontario pour 
l'eau potable. 

Pour environ 110 parametres organiques mesures, aucun resultat n'a 
depass6 les limites acceptables fixees pour la sante . 

Un grand nombre de substances detectees apparaissent naturellement 
ou sont des produits derives de l'epuration. 

Les resultats des analyses effectuees en 1987 dans le cadre du 
PSEP ont indique que la station d'epuration de Stoney Point 
donnait une eau de bonne qualite.

STONEY POINT WATER TREATMENT PLANT 
1937 ANNUAL REPORT 



INTRODUCTION 

The Drinking Water Surveillance Program (DWSP) for Ontario is a 
monitoring program providing immediate, reliable, current 
information on drinking water guality. The DWSP officially began 
in April 1986 and is designed to eventually include all municipal 
supplies in Ontario. Currently, 44 plants are being monitored. 
Appendix A contains a detailed description of the DWSP. 

The DWSP was initiated at the Stoney Point Water Treatment Plant 
in April 1986. An annual report was published in 198 6 (ISBN 0- 
7729-2566-6) . 

This report contains information and results for 1987. 

PLANT DESCRIPTION 

The Stoney Point Water Treatment Plant is a conventional 
treatment plant which treats water from Lake St. Clair. The 
process consists of coagulation, flocculation, sedimentation, 
filtration and disinfection. The plant serves a population of 
3,500 people. The treatment plant has a design capacity of 4.45 
x 100Gm3/day. 



The plant location is shown in Figure 1. Plant process details 
are shown in Figure 2. General plant information is presented 
in Table 2. 

METHODS 

Water samples were obtained from two DWSP approved locations; 
i) Raw - The water originated from the lowlift 

discharge and was sampled through a copper 
sample line. The sample tap is located at 
the lowlift discharge, 
ii) Treated - The water originated from the highlift 
discharge after addition of all treatment 
chemicals and was sampled through a copper 
sample line. The sample tap is located in 
the plant laboratory. 

Sample lines in the plant were flushed prior to sampling to 
ensure that the water obtained was indicative of its origin and 
not residual water standing in the sample line. 

Attempts were made to capture the same block of water at each 
sampling point by taking the retention time into consideration. 
The retention time was calculated by dividing the volume of water 
between the two sampling points by the sample day flow. For 
example, if it was determined that the retention time within the

plant was five hours then there would be a five hour interval 
between the raw and treated sampling. 

Stringent DWSP sampling protocols were followed to eliminate any 
variance (Appendix B) . 

Sample day flow, treatment chemical dosages and field 
measurements such as Turbidity, Chlorine Residuals, pH and 
Temperature were recorded on the day of sampling and were entered 
onto the DWSP data base as submitted. 

RESULTS 

Water at the Stoney Point Water Treatment Plant was sampled for 
approximately 160 parameters in June and November 1987. 

Table 3 contains information on the sample day retention time, 
flow rate and treatment chemicals used and their associated 
dosages. 

Table 4 is a summary break-down of the number of water samples 
analysed for by parameter and by water type. The number of times 
that a positive or trace result was detected is also reported. 

Positive denotes that the result is greater than the statistical 
limit of detection established by the Ministry of Environment 
(MOE) laboratory staff and is quantifiable. Trace (<T) denotes 



that the level measured is greater than the lowest value 
detectable by the method but lies so close to the detection limit 
that it cannot be confidently quantified. 

Table 5 presents the results for parameters detected on at least 
one occcasion. 

Table 6 presents parameters not detected. 

Associated guidelines and detection limits are also supplied on 
both tables. Parameters are listed alphabetically within each 
scan. 

DISCUSSION 

General 

Water quality is judged by comparison with the Ontario Drinking 
Water Objectives (ODWOs) as defined in the 1984 publication (ISBN 
0-7743-8985-0) . The Province of Ontario has health related and 
aesthetic objectives for 49 parameters, these are currently under 
review. When an ODWO is not available guidelines/limits from 
other agencies are consulted. The Parameters Listing System 
(PALIS) recently initiated by the MOE catalogues and keeps 
current over 1750 guidelines for 650 parameters from agencies 
throughout the world. 



As stated under Results, traces do not indicate quantifiable 
results as defined by established MOE laboratory analytical 
reporting protocols. While they can be useful in trend analysis 
or confirmation of the presence of a specific contaminant that 
is repeatedly detected at these levels, the occasional finding 
of a trace level of a contaminant is not considered to be 
significant. DISCUSSION OF GUIDELINES AND LIMITS THEREFORE, IS 
ONLY CONDUCTED ON POSITIVE RESULTS. 

Bacteriology 

Positive results were present two times in the treated water. 
These results were Standard Plate Count and Total Col i form 
Background. No ODWOs were exceeded. 

Due to the sampling frequency, the bacteriological quality of 
water could not be fully evaluated. Routine bacteriological 
monitoring as recommended in the ODWOs is carried out by the 
operating authority. 

Inorganic and Physical 

Laboratory and Field Chemistry 

The results for the Laboratory Chemistry and Field Chemistry 
scans were below all applicable health related ODWOs.

It is desirable that the Temperature of drinking water be less 
than 15°C; the palatability of water is enhanced by its coolness. 
A temperature below 15°C will tend to reduce the growth of 
nuisance organisms and hence minimize associated taste, colour, 
odour and corrosion problems. The desired ODWO was exceeded in 
one of the treated waters. 

Metals 

The results reported for the Metals scan were below any 
applicable health related ODWOs. 

Organic Parameters 

Chloroaromatics 

The results of the Chloroaromatics scan showed that no 
Chloroaromatics were detected. 

Chlorophenols 

The results of the Chlorophenols scan showed that no 
Chlorophenols were detected. 

Pesticides and PCB (Polychlorinated Biphenyls) 

The results of the Pesticides and PCB scan showed that one 
pesticide was detected: 
Alpha BHC 

Lindane consists of several isomers of BHC (Benzene 
Hexachloride) . Alpha BHC is the most predominant isomer found 



in the water of the Great Lakes Basin, as indicated in results 
from other water supplies on DWSP. 

Alpha BHC was detected at trace levels once in the raw water and 
twice in the treated water. 

Specific Pesticides 

Results of the Specific Pesticides scan showed that no parameters 
were detected. 

Phenol ics 

Phenolics were detected at trace levels, once in the raw water 

and the treated water. Phenolic compounds are present in the 

aquatic environment as a result of natural and/or industrial 

processes. 

Polynuclear Aromatic Hydrocarbons (PAH) 

The results of the PAH scan showed that no PAHs were detected. 



Volatiles 

The results of the Volatiles scan showed that one parameter other 
than Trihalomethanes(THMs) , was detected: 
1,1, 1-Trichloroethane 

1, 1, l-Trichloroethane was detected at a trace level, once in the 
raw water. 



THMs are acknowledged to be produced during the water treatment 
process and will always occur in chlorinated surface waters. 
THMs are comprised mainly of Chloroform, Chlorodibromomethane and 
Dichlorobromomethane. Bromoform occurs occasionally. Results 
are reported for the individual compounds as well as for total 
THMs. 

Chloroform, Chlorodibromomethane, Dichlorobromomethane and Total 
THMs were detected in all of the treated water samples. Bromoform 
was detected at trace levels, in both treated water samples. All 
THM occurrences were well below the ODWO of 350 ug/1 for Total 

THMs. 

Comparison with the results from the DWSP for 1986 show that the 
raw and treated water quality from 1986 and 1987 has remained 
consistent. 

CONCLUSIONS 

The Stoney Point Water Treatment Plant for the sample year of 
1987 produced good quality water at the plant. 

No health related guidelines, for organic or inorganic 
parameters, were exceeded during 1987.

RECOMMENDATIONS 

One recommendation can be made: 

1) The data base should be reviewed in consultation with 
Regional, Plant and DWSP personnel to determine if sampling 
location, sampling frequency and the number of parameters 
analysed could be revised to allow for a more efficient 
characterization of the water.

A ONTARIO DRINKING WATER OBJECTIVES 

1. Maximum Acceptable Concentration (MAC) 
1+. MAC for Total Trihalomethanes 

1*. MAC for Bacteriological Analyses 

Poor water quality is indicated when : 

- total coliform counts > < 5 

- P/A Bottle Test is present after 48 hours 

- Aeromonas organisms are detected in more than 

25% of samples in a single submission or in 
successive submissions from the same sampling 
site 

- Pseudomonas Aeruginosa, Staphylococcus Aureus 

and members of the Fecal Streptococcus group 
should not be detected in any sample 

- Standard Plate Count should not exceed 500 
organisms per ml at 3 5 deg C within 48 hours 

2. Interim Maximum Acceptable Concentration (IMAC) 

3. Maximum Desirable Concentration (MDC) 

4. Aesthetic or Recommended Operational Guideline 

- hardness levels between 80 and 100 mg/L as 
calcium carbonate are considered to provide an 
acceptable balance between corrosion and 
incrustation, water supplies with a hardness 
>200 mg/L are considered poor and those in 
excess of 500 mg/L are unacceptable.

DRINKING WATER SURVEILLANCE PROGRAM 

The Drinking Water Surveillance Program (DWSP) for Ontario 
monitors drinking water quality at municipal water supply 
systems. The DWSP Database Management System provides a 
computerized drinking water quality information system for the 
supplies monitored. The objectives of the program are to provide: 

- immediate, reliable, current information on drinking 
water quality, 

- a flagging mechanism for 'Objective' exceedence, 

- a definition of contaminant levels and trends, 

- a comprehensive background for remedial action, 

- a framework for assessment of new contaminants, 

- and an indication of treatment efficiency of plant 
processes. 

Program 

The DWSP officially began in April 1986 and is designed to 
eventually include all municipal water supplies in Ontario; 
currently 44 plants are being monitored. Water supply locations 
have been prioritized for surveillance, based primarily on 
criteria such as population density, probability of contamination 
and geographical location. 



An ongoing assessment of future monitoring requirements at each 
location will be made. Monitoring will continue at the initial 
locations at an appropriate level and further locations will be 
phased into the program as resources permit. It is estimated that 
after 4 years of operation, the program will be monitoring 90 
locations. 

A major goal of the program is to collect valid water quality 
data, in context with plant operational characteristics at the 
time of sampling. As soon as sufficient data have been 
accumulated and analysed, both the frequency of sampling and the 
range of parameters may be adjusted accordingly. 

Assessments are carried out at all locations prior to initial 
sampling in order to acquire complete plant process and 
distribution system details, and to designate ( and retrofit if 
necessary ) all sampling systems and locations. This ensures that 
the sampled water is a reflection of the water itself. 

Samples are taken of the raw ( ambient water ) and the treated 
water at the treatment plant, and of consumer's tap water in the 
distribution system. In order to determine possible effects of 
distribution on water quality, both standing and free flow water 
in old and new sections of the distribution system are sampled. 

Sampling is carried out by operational personnel who have been 
trained in the applicable procedures. 



11 



Comprehensive standardized procedures and Field Test kits are 
supplied to sampling personnel. This ensures that samples are 
taken and handled according to standard protocols and that field 
testing will supply reliable data. All field and laboratory 
analyses are carried out using "approved documented procedures". 
All laboratory analyses are carried out by the MOE Laboratory 
Services Branch. 

Data Reporting Mechanism 

When the analytical results are transferred from the MOE 
laboratory into the DWSP system, printouts of the completed 
analyses are sent to the MOE District Officer, the appropriate 
operational staff and are also retained by the DWSP co-ordinator . 



DWSP INPUTS AND OUTPUTS 

The DWSP INPUTS and OUTPUTS are illustrated in Fig. 1. 

PROGRAM INPUTS 

PLANT AND DISTRIBUTION SYSTEM DESCRIPTION 

The system description includes plant specific non-analytical 
information acquired through a questionnaire and initial plant 
visit. During the initial assessment of the plant and 
distribution system the questionnaire content is verified and 

iii 



missing information added. It is intended that all data be kept 
current with scheduled annual updates. 

The PLANT and DISTRIBUTION SYSTEM DESCRIPTION consists of the 
following seven components. 

1. Process component inventory 

All physical and chemical processes that the water is subjected 
to, from the intake pipe to the consumers' tap (where possible), 
are documented. These include: process type, general description 
of physical structures, material types, sizes, and retention time 
for each process within the plant. The processes may be as simple 
as transmission or as complex as carbon adsorption. 

2 . Treatment chemicals 

Chemicals used in the treatment processes, their function, 
application point, supplier and brand-name are recorded. The 
chemical dosages applied on the day of sampling are recorded in 
DWSP. 

3 . Process control measurements 

Documentation of in-plant monitoring of process parameters 
(turbidity, chlorine residuals, pH, aluminum residuals) including 
methods used, monitoring locations and frequency is contained in 
this section. In-plant monitoring results are generally not 
retained in DWSP but are retained by the Water Treatment Plant. 



IV 



4. Design flow and retention time 

The hydraulic capacity, designed and actual, is noted here. 
Retention time (the time that a block of water is retained in 
the plant) is also noted. The maximum, minimum and average flow 
as well as a record of the flow rate on the day of sampling are 
recorded in DWSP. 

5. Distribution system description 

This area includes the storage and transmission characteristics 
of the distribution system after the water leaves the plant. 

6. Sampling system 

Each plant is assessed for its adequacy in terms of sampling of 
bacteriological, organic and inorganic parameters. The prime 
considerations in the assessment and design of the sampling 
system are: 

i/ the sample is an accurate representation of the 

actual water condition, eg. raw water has had no 

chemical treatment; 
ii/ the water being sampled is not being modified by the 

sampling system; 
iii/ the sample tap must be in a clean area of the plant, 

preferably a lab area; 
iv/ the sample lines must be organically inert (no 

plastic, ideally stainless steel) . 



It is imperative that the sampled water be a reflection not of 
the sampling system but of the water itself. 

The sampling system documentation includes: origin of the water; 
date sampling was initiated; size, length and material type 
(intake, discharge and tap), pump characteristics {model, type, 
capacity) and flow rate. 

7. People 

This section contains the names, addresses and phone numbers of 
current plant management and operational staff, distribution 
system management and operational staff, Medical Officer of 
Health and appropriate Ministry of Environment personnel 
associated with the plant. 

FIELD DATA 

The second major input to DWSP is field data. 

Field data is collected at the plant and from the distribution 
system sites on the day of sampling. The field data consists of 
general operating conditions and the results of testing for field 
parameters. General operating conditions include chemicals used, 
dosages, flow and retention time on the day of sampling as well 
as monthly maximum, minimum and average flows. Field parameters 
include turbidity, chlorine residuals (free, combined and total) , 
temperature and pH. These parameters are analysed according to 
standardized DWSP protocols to allow for interplant comparison. 



vi 



LABORATORY ANALYTICAL DATA 

The third major input to DWSP is Laboratory Analytical Data. 

Samples gathered from the raw, treated and distribution sampling 
sites are analyzed for approximately 160 parameters at a 
frequency of two to twelve times per year. Sixty-five percent of 
the parameters are organic. The parameters measured may have 
health or aesthetic implications when present in drinking water. 
Many of the parameters may be used in the treatment process or 
may be treatment by-products. Due to the nature of certain 
analytical instruments parameters may be measured for in a "scan" 
producing some results for parameters that are not on the DWSP 
priority list but which may be of interest. The majority of the 
parameters are measured on a routine basis however, those that 
are technically more difficult and/or costly to analyse for are 
done less frequently. These include Specific Pesticides and 
Chlorophenols . 

Although the parameter list is extensive, additional parameters 
with the potential to cause health or aesthetic related problems 
may be added provided reliable analytical and sampling methods 
exist. 

All laboratory generated data is derived from standardized, 
documented analytical protocols. The analytical method is an 
integral part of the data and as methods change notation will 
be made and intercomparison data documented. 

vii 



PARAMETER REFERENCE INFORMATION 

The fourth major input to DWSP is Parameter Reference Information 

This is a catalogue of information for each substance analysed 
on DWSP. It includes parameter name and aliases, physical and 
chemical properties, basic toxicology, world-wide health limits, 
treatment methods and uses. The Parameter Reference Information 
is computerized and can be accessed through the Query function 
of the DWSP database. 

An example is shown in fig. 2. 

A written copy (hard version) of the Parameter Reference 
Information will be available in the near future and is a new and 
sophisticated enhancement to the DWSP. 

PROGRAM OUTPUTS 

There are four major program outputs, Query, Action Alert, Report 

Generation and the Annual Report. 

QUERY 

All DWSP information is easily accessed through the Query 
function, therefore anything from addresses of plant personnel 
to complete water guality information for a plant's water supply 
is instantly available. Ths DWSP computer system makes relatively 
complex inquiries manageable. A personal password allowing access 
into the DWSP query mode in all MOE offices is being developed 
by the DWSP group. 

viii 



ACTION ALERTS 

Drinking Water quality in Ontario is evaluated against provincial 
objectives as outlined in the publication, Ontario Drinking Water 
Objectives (ISBN 0-7729-2725-1 revised 1983). This publication 
contains health-related Maximum Acceptable Concentrations for 
thirty substances . Should the reported level of a substance in 
treated water exceed the Ontario Drinking Water Objective an 
"Action Alert" requiring resampling and confirmation is issued. 
This assures that operational staff, health authorities and the 
public are notified as soon as possible of confirmation of an 
exceedance and remedial action taken. This report supplies a 
history of the occurrence of past exceedences at the plant plus 
a historical summary on the parameter of concern. 

In the absence of Ontario Drinking Water Objectives, other agency 
guidelines which are documented in the Parameter Reference 
Information may be used. If these guidelines are exceeded the 
results are flagged and evaluated by DWSP personnel. An "Action 
Alert" will be issued if warranted. 

REPORT GENERATION 

Custom reports can be generated from DWSP to meet the needs of 

the regions and to respond to public requests. 

ANNUAL REPORTS 

It is the practice of DWSP to produce an annual report containing 

analytical data along with companion plant information.
